Help me get my head around some big numbers...

The jet propulsion for your rocket could run on ethanol.
This is what the Germans ran the V2 rocket on, basically ethanol is potato vodka.
From memory it was something like 40 tonnes of potatoes to power one V2 rocket

To see how potatoes can be grown in space see the film 'The Martian' where person castaway on Mars survives on potatoes.
Potatoes can be grown vertically in gel, so you dont need a lot of space (Check out the real growing methods at Thanet Earth)

So you think that speculating about space travel pre-twentieth century and the laws of physics is the same as obsessing about a cartoon?

Nah, more like this

No, it is the fact that some people take plot holes in fictional stories a little too seriously than they should, instead of just enjoying the story.

a; it's clockwork
b; i avoid films starring Matt Damon like the plague... in fact, I'd rather get the plague

and I'm trying to work out its average speed

I'm late to the party, but it's gone 6 light years in 200 years. So it's 3 light years per century, and if you type "3 light years per century in mph" into google it'll confirm you're right.

 

[MontyVeda]

I would leave it at that and not attempt to explain it any further at all.

good advice... if a bit late.

That depends if you want to write a science fiction or a fairy tale.

oh i dunno... why get bogged down with minor details? I must've spent (wasted) an hour trying to work out the average speed of my starship, a detail that takes up no more than a single sentence.

Perhaps I should have emphasised the "type into google" bit. It amuses me that the power of the world's computers is available to those of us wanting to know how chains per second convert into cubits per day

Plot thoughts - years ago I read a novel by - I think - Anthony Burgess that was mostly the story of an interstellar ship leaving earth. Eventually it's revealed that this story is being told to the nth generational descendants on board. But they don't believe it. They live in this huge hulk, without windows. They believe this hulk is the extent of the universe. They do not believe in Earth, or their destination. They do not know of the universe just outside their domain.

I think that's 'Orphans of the Sky' by Robert Heinlein https://en.wikipedia.org/wiki/Orphans_of_the_Sky

sorry... i was focusing on the 'it'll confirm you're right' bit.

LOX / MEOH rockets are soooooo last year.
